Overview
KAL's Calcium Citrate delivers 1,000 mg of calcium per serving in unflavored tablets, packaged as 180 tablets covering 60 servings, and marketed around bone, teeth, nervous, muscular and cardiovascular support.
Calcium citrate is a form some people take specifically because it doesn't require stomach acid for absorption the way calcium carbonate does, which is likely why this listing specifies citrate rather than a cheaper carbonate form. At 180 tablets for 60 servings, each serving works out to three tablets, worth noting before comparing price per bottle against single-tablet products.
